hw/misc: Don't special case RESET_TYPE_COLD in npcm7xx_clk, gcr

The npcm7xx_clk and npcm7xx_gcr device reset methods look at
the ResetType argument and only handle RESET_TYPE_COLD,
producing a warning if another reset type is passed. This
is different from how every other three-phase-reset method
we have works, and makes it difficult to add new reset types.

A better pattern is "assume that any reset type you don't know
about should be handled like RESET_TYPE_COLD"; switch these
devices to do that. Then adding a new reset type will only
need to touch those devices where its behaviour really needs
to be different from the standard cold reset.
